elfstructs: add relocation defines for i386

Those are need by the rombios relocation code in hvmloader. Fixes the
following build error:

32bitbios_support.c: In function 'relocate_32bitbios':
32bitbios_support.c:130:18: error: 'R_386_PC32' undeclared (first use in this function); did you mean 'R_X86_64_PC32'?
             case R_386_PC32:
                  ^~~~~~~~~~
                  R_X86_64_PC32
32bitbios_support.c:130:18: note: each undeclared identifier is reported only once for each function it appears in
32bitbios_support.c:134:18: error: 'R_386_32' undeclared (first use in this function)
             case R_386_32:
                  ^~~~~~~~

Only add the two defines that are actually used, which seems to match
what we do for amd64.
